What ports and IP addresses does Lish use? The corporate firewall is blocking access.
Our corporate firewall is blocking access to the Lish Console, the Grahical Lish Console, and the console via the Linode Cloud Manager.
Lish via SSH works fine on port 443.
I am sure that it is our firewall, because if I connect via my mobile phone, it all works wonderfully!
I have searched through the community site, but haven't come across any firewall information.
Could you please let me know what ports/protocols need to be allowed by our corporate firewall, along with the range of I.P. addresses used to connect to Linode (I believe that our firewall rules are applied to specific addresses or address ranges).
Great question. Each datacenter has its own Lish gateway. Performing a dig command against the URL of the Lish gateway you're trying to connect to, is the best way to find the IP address you need to allow through your firewall. If your Linode is in the London data center, you'll need to find the IP address of the London Lish gateway. Here's an example of that looks like:
dig london.webconsole.linode.com ; <<>> DiG 9.10.6 <<>> london.webconsole.linode.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 16125 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;london.webconsole.linode.com.

Here's where you can find a list of all our Lish gateways. I recommend verifying the IP address of the Lish gateway because those addresses may be subject to change in the future.
Lish uses ports 22, 443, 2200 and 8181.
